When the analysis of population density is done by calculating it through net cultivated area, then the measure is termed as:

Correct option is B

·When population density is calculated based on the net cultivated area, the measure is actually termed physiological density, not agricultural density.

· Physiological density refers to the number of people per unit of arable land (land that is suitable for cultivation).

· It helps in understanding how many people depend on the land for food production and how much land is available to support that population.

Additional Information:

·  Physiological density gives a better sense of the carrying capacity of land. It helps to assess the pressure of population on the agricultural land in a region. A higher physiological density suggests a greater dependency on agriculture and a potential strain on land resources.

Other Options:

· Agricultural density: Agricultural density specifically focuses on the number of people engaged in agriculture per unit of cultivated land. It's more specific than physiological density, which looks at the overall population relative to arable land, not just those engaged in farming.

· Gross density: This measure is the total population divided by the total land area (including both cultivated and uncultivated land), not just the arable land.

· Net density: This term isn't commonly used in geography or population studies, and it is not a standard term in this context.
